Thermochill rad flux cleanup

[Zaskar]

Good grief...could this be the main reason for clouding? hahaha

Id bet on it.

After reading what most people (even the stickied ones) suggest and do, its just simply not enough.

You can Not get these rads perfectly clean from adding water and shaking alone.

BTW eternal_fantasy, the rust you see, is it on the outside? If so that IS rust, TC rads have a steel casing and with that CRAPPY quality matte non sealing paint, it lets water soak RIGHT THROUGH it and contact the steel, meaning any water spilled on the rad casing itself will cause some surface rust to come up through the paint. Its a radiator that you cant get wet on the outside... Awesome design, Definitely worth not having to spend 5-8 bucks more for stainless sheet metal...
